John Deere D105 lawn tractor

John Deere has earned a reputation for itself when it comes to outdoor power equipment, tractors, lawn mowers and lawn tractors. When it comes to lawn tractor machines they make some of the best available.

John Deere caters to a wide audience when it comes to lawn tractors. They make the entry-level lawn tractors as well as lawn tractors and zero turn mowers for commercial usage.

In this review we will take a close look at the very popular John Deere D105 lawn mower which is one of the best entry-level lawn tractors on the market at the moment. We will not only go into the features of this lawn tractor but also share with you some of the pros and cons of the machine to help you understand whether it is the best option for you.

About the John Deere D105:

The John Deere D105 is powered by a John Deere branded engine which produces a very reasonable 17.5 HP making this machine a true garden workhorse.

If you look at the lineup of John Deere lawn tractors, you would realize that this one packs the best punch under its hood. It is also the most budget-friendly lawn tractor option.

John Deere D105The high quality build of this lawn tractor and its dual blade set-up ensures that you are able to get precise cut in a single go without having to run over the lawn again.

You can either opt for the mulch discharge or the side discharge or even use the rear discharge if you attach a bagger.

With a forward speed of 5.5 mph, you can easily cover an area of up to 2 acres using this lawn tractor. The D105 also offers a top reverse speed of 3.2 mph with the ability to cut in reverse also.

We’ve mentioned this in other reviews but it is worth noting again – don’t attempt to reverse mow at top speed on any riding mower unless you very flat and even terrain or you run a very high risk of scalping your lawn.

The transmission type of the D105 is automatic.

In order to clean the cutting deck, a wash port is present; simply hook up a standard garden hose and turn on the water and the deck and blades will be cleaned automatically. We urge you to do this after every use.

The automatic transmission is smooth helping for a more relaxing operation. Although this lawn tractor is not as noisy as the larger machines you may still want to wear some ear protection.

OEM Engine:

Most of the john Deere d105 reviews state that the 17.5 HP engine is more than adequate for normal to hilly lawns up to approximately 2 acres in size.

The D105’s engine offers more than enough power for trimming, mowing, bagging and mulching as well as towing and operating a wide variety of add-ons such as a cart, aerator, spreader, snow plough etc.

John Deere D105 OEM engine

The single cylinder engine uses electronic ignition which ensures that the lawn tractor starts first time.

The durability of the engine is further increased due to the fact that it is placed inside a cast iron sleeve.

The overhead valves add to the fuel as well as power and efficiency of the engine so you burn less fuel and run the mower for longer periods.

One of the unique factors of the engine is the anti-vibration feature. This ensures that you are able to comfortably sit on the lawn tractor without experiencing high vibrations and also lower the overall noise levels.

The engine uses an oil filter which ensures that you do not have to change the oil as frequently as you would have to do on other models. This not only increases the life-span of the engine but also reduces the maintenance needed.

Also, whenever you want to change the oil you can use the oil drain valve which will drain the remaining oil from the engine (which we recommend you do when winterizing your machine) and thereby, makes it easier for you to fill the new oil.

The fuel filter included in the D105’s engine is large compared to it’s peers which makes it easier for you to run the lawn tractor for longer without the need for a filter change.

Horse Power:

The engine sports a very respectable 17.5 Horse Power which offers more than enough power to  ensure that you are able to easily move the lawn tractor even on steep inclines.

d105 john deere lawn tractorThe torque which is produced by the engine is more than enough for mulching, bagging as well as mowing most lawns even those with challenging terrain.

Even though the D105 handles well and offers a good cut across a range of terrain types if you do have rough ground and very steep inclines then it just may not be powerful enough for your needs.

However, for average American lawns this entry-level garden tractor is more than sufficient.

Starting System and Transmission:

The John Deere D105 has a keyed starting mechanism.

The engine has an electronic ignition system which ensures that there is no waiting time and the engine starts quite quickly – pretty much first time, every time.

The lawn tractor comes with automatic transmission with a single foot pedal speed control just like any other standard automatic vehicle.

You can control both the forward as well as reverse speed in the same manner you would control a car or jeep.  The engine is very responsive and gear changes smooth.

Cutting Deck and Blades:

The cutting deck measures 42 inches giving a good wide area cut with every pass.

The cut quality is as you would expect from a John Deere mower and you should have no complaints from the dual blade performance.

John Deere cut height leverThe cut height can be easily adjusted from 1″. to 4″ in 1/4 ” increments via a single lever.

The cutting deck is also rolled outwards which provides you with enhanced protection from any flying debris that the might be thrown out by the blades.

This feature also adds to the strength of the lawn tractor.

The cutting deck is coated with that dual stage E-coat which protects it against rust as well as other forms of corrosion.

The body work is very durable and the mower should stay in tip-top condition as long as perform even the basic maintenance on it. Basically, if you look after the D105 it should last you a very long time needing only occasional blade sharpening or replacement.

In order to wash the deck, a wash port is included and can be used with a standard garden hose. Just hook up the hose to hose connector, turn on the water and let the water blast clean the deck automatically.
